Followed the tutorials on setting everything up, cloned 4.4 to my hard drive, downloaded the required dependencies ( 2 of ), merged them into the github folder.
The 4.4 Branch is not the same as the 4.4.0 you find in the launcher, it is being updated with 4.4.1 and other changes so the dependencies and hell the code might not compile right yet lol =)
The Error List only provides a summary of the error, if you double-click on the error and switch to the Output window is there any additional information about the error?
